Based on best practices, we recommend the following:
(d) Retain a small part of the private key or recovery seed. For e.g. if you are using a
Ledger Wallet which generates a 12 words recovery seed, you may want to only
input 11 words into the INF vault and keep the last word separately on paper.
(e) Spilt up the private keys into several vaults.
(f) Use a mixture of delivery methods.
